      These error are coming because you don't have target runtime set to apache tomcat 7. Use apache tomcat 7 and set target runtime to it, that will resolve compilation errors. Please take your time and read steps given above properly.

    I would totally recommend Photo4Tune as an alternative for Whatsapp and Snapchat. It has got amazing emoticons, simple user interface for photo sharing.

    We have integrated this in one of our web application. This worked fine with all the expected functionalities while testing using our office network, where all the machines are connected in LAN (locally). We mapped a public IP to the server and tried to access it using public IP outside of our office network which showed up the problem. Whatever is sent from the internet is received in the machines logged in within our office network, however the messages sent from machines within our office network are not received in the machines connected outside of our network.

    We are hardly trying to find out some solution to fix this issue. Any help will be highly appreciable. Thanks in advance.
